Wedding in a month Help

Im about to shoot a wedding by my self (1st time by myself) and i have questions. The wedding is actually going to be for a 77 yr old man and 72 yr old woman. I know its going to be alot diff then a normal wedding since they wont really want to do as much as a younger couple. But how can i pose them? Should i just pose them like i normally would? Also idk how i can do it, but they want there formal shots/ group shots and family shots in 15 mins. Any help would be great.

Pose them the same you would for anyone else.

Also YOU need to let them know that portraits take more than 15 minutes. If that's all they have recommend you do some before the ceremony, otherwise all you will have time for is one large group shot and a few of just the bride and groom and that's it. Take control of the situation.

Yea im waiting for there call to confirm everything first.

Respect their cultural and historically-related preferences for photo style and integrate that with your methods that drew them to you in the first place. To know what they prefer, you must ASK.

The key is the lighting. It's going to be tough to get flattering shots with bad lighting. Is this indoors or outdoors, will you be using flash? Are they wearing glasses? Do they need to sit down or can they stand for a long period of time? There are a lot of questions for older couples. Also, if you seat them in the center of a group shot, that is actually not a bad way to go. Put the others around them, but make sure they are sitting as straight as possible.

20 minutes for family photos. 30 minutes for photos of the two of them. I'd stay reasonably formal, but depending on the couple i'd do both classic and modern.

I've photographed 60 year olds who act more like teenagers than 20-30 year olds.
